Movie Grab (http://ambrielsoftware.com/products/movie_grab/) is actually shareware, but you can download and use it to make screen movies. The software company that makes it says it's no longer selling the product, so this page may not be up for long. I've used this, and it seems to work fine (video capture only).

Also, a tool called Screenography for the Mac captures natively to both Flash and QuickTime. It's only $40. I haven't tried it out yet myself, but plan to.
